The Bawden family is shopping for a new television. They are making their decision based on brand and size. The family has 20 possible outcomes for choosing a television. Which is a possible number of brands and sizes that the family has to choose from?

Use the multiplication principle: the number of possible brand-and-size combinations equals the number of brands multiplied by the number of sizes. For choice B, 5 brands × 4 sizes = 20 possible outcomes. The other choices produce more than 20 outcomes.
